BDSM Pushing Boundaries Part 3

When we return to London River in her live feed, it is pretty clear that she has been pushed a little beyond her limits. She can't get her hands to work in order to tie her own ankles. She keeps slipping and her hands are shaking. It's her own fault for coming up with so many ridiculous, brutal torments for herself. And what's worse is she hasn't even gotten to the hardest of them yet. In her final installment, we are going to find out if London can hold herself together when pushed farther beyond her limits than she has ever been pushed.
The first plan we have was one of London's own ideas. If you are a regular viewer, you are no doubt familiar with the concept of the zipper: a line of clothespins clipped onto skin and attached to each other by a string. When ripped off, the pain is absolutely excruciating. London, sadistic bitch that she is, has decided that there is room for improvement on this time honored classic. She has decided it is necessary to be bent back over a bench with her wrists and ankles tied to the floor to tighten the skin on her stomach. What's more, she came up with the idea to replace the clothespins with binder clips. With a hitachi between her legs, when the string is pulled, the sound that comes out of her is truly something to behold.
